SPECIFICATIONS

The Model 428-PROG Programmable Current Amplifier converts fast, small currents to a voltage, which can be easily digitized or displayed by an oscilloscope, waveform analyzer, or data acquisition system. It uses a sophisticated "feedback current" circuit to achieve both fast rise times and sub-picoamp noise. The gain of the Model 428-PROG is adjustable in decade increments from 103V/A to 1011V/A, with selectable rise times from 2μs to 300ms.

The maximum current is really dependent on the gain setting range. The 428 is not a measuring instrument, but rather an amplifier. Since the maximum voltage is 10V, then the maximum current that can be applied is 10mA (10^3 gain setting).
  • 2μs rise time
  • 1.2fA rms noise
  • Up to 1011 V/A gain
  • GPIB interface
